Stephanie gets it!
To achieve perfect frying results, you need practical solutions for optimal oil management. Stephanie is here to help you find them.
Perfect frying results every time.
Thanks to smart oil management.
Crispy, golden brown and delicious – fried food should always be this good. The quality of the frying oil plays a crucial role: If the oil gets too old, unwanted compounds can quickly form, affecting the taste, texture and safety of the food. By regularly determining the optimal TPM value*, you will know exactly when to change the oil – which will allow you to optimize its lifespan, reduce costs by up to 20 percent and ensure the high quality of your fried products.
* TPM = Total Polar Materials; an indicator of the degree of fat degradation during frying

5 expert tips from Stephanie
During frying, the oil becomes part of the food, strongly influencing its taste, texture, shelf life and nutritional value. The optimal range is a medium TPM zone, as this ensures the best balance of flavour development, browning and oil absorption.
Oil that is too fresh often results in soft, pale fries without a crust. Conversely, overused oil quickly makes fries dark, hollow, rancid and greasy. The ideal therefore is slightly used oil, from which water can escape in a controlled manner, allowing flavours to develop fully.
Around 175 °C/347 °F provides enough energy for quick crust formation without putting unnecessary stress on the oil – making this a reliable guideline. The benefits to you: longer oil life, more consistent quality, a lower risk of acrylamide formation and improved cost efficiency.
Water, atmospheric oxygen, breading, spices, salt and high temperatures all promote oxidation and polymerization. Filter your frying oil regularly, protect it from light and contaminants, and avoid overheating to maintain its quality for longer.
Look out for warning signs such as a darker colour, fine foaming, a rancid smell or thicker viscosity. However, don’t change the oil based on a “gut feeling” – use objective measurements to make audit-proof, reproducible decisions.
“The quality of frying oil is an often underestimated factor. Yet it has a direct impact – on taste, health and profitability.”
